Sonoanatomy of the lateral antebrachial cutaneous nerve. A Short-axis view of the lateral antebrachial cutaneous nerve at the lateral aspect of the antecubital fossa. The nerve appears as small honeycomb structure lying superficially lateral to the biceps tendon and deep to the cephalic vein (the vein is compressed in this image). B A zoomed image with releasing the pressure by the probe to expand the cephalic vein showing the lateral antebrachial cutaneous nerve lying deep to the vein and directly lateral to the biceps tendon
